Y'know, that might actually work. Bring a 1x2 plate and tack the dead body to the plate, he'd be lying down...

...then again, that would interrupt squad maneuvers. Here's an idea. Each faction has a certain color baseplate. The dead are usually gathered in battle lines anyway, so when a mini goes down, it gravitates to the nearest deadplate, where the faction's dead are lain...

And we could have temporary bonuses for having the largest piles of enemy bodies on a nearby deadplate.
